13 SPI busses can be described with a node for the SPI controller device
14 and a set of child nodes for each SPI slave on the bus. The system SPI
15 controller may be described for use in SPI master mode or in SPI slave mode,
20 pattern: "^spi(@.*|-([0-9]|[1-9][0-9]+))?$"

H A Dqca,qca7000.txt3 The QCA7000 is a serial-to-powerline bridge with a host interface which could
4 be configured either as SPI or UART slave. This configuration is done by
7 (a) Ethernet over SPI
9 In order to use the QCA7000 as SPI device it must be defined as a child of a
10 SPI master in the device tree.
13 - compatible : Should be "qca,qca7000"
14 - reg : Should specify the SPI chip select
15 - interrupts : The first cell should specify the index of the source
18 - spi-cpha : Must be set
19 - spi-cpol : Must be set

H A Dmicrochip,enc28j60.txt3 This is a standalone 10 MBit ethernet controller with SPI interface.
5 For each device connected to a SPI bus, define a child node within
6 the SPI master node.
9 - compatible: Should be "microchip,enc28j60"
10 - reg: Specify the SPI chip select the ENC28J60 is wired to
11 - interrupts: Specify the interrupt index within the interrupt controller (referred
12 to above in interrupt-parent) and interrupt type. The ENC28J60 natively
15 - pinctrl-names: List of assigned state names, see pinctrl binding documentation.
16 - pinctrl-0: List of phandles to configure the GPIO pin used as interrupt line,
21 - spi-max-frequency: Maximum frequency of the SPI bus when accessing the ENC28J60.
